Fin Lock Ring 4 Fin - 19344

Finally got my fins to stay put during launch prep; this ring holds them tight without any extra glue mess. Perfect fit for standard 4-fin builds.

The ring slides on with just the right amount of friction, so my fins stay put during the build without needing extra force. I appreciate that it’s a dedicated 4-fin design, which makes alignment much less fiddly than improvising with tape.

Finally got my rocket fins secured properly after trying glue alone on my last build — this ring locks them in place exactly as described. The plastic is sturdy enough to hold through multiple flights without cracking, which was my biggest worry.
